Used these a number of years ago to create a raised garden bed. They shifted like crazy when full of dirt even with rebar down the center. Once I got them figured out though, they were really successful for my garden.

Tips:
-Use Rebar even though its not going to help a lot
-spend more time than you want prepping and leveling
-If more than 2 courses high, install 2x6 corner braces spanning 2 courses to lock each down. Think hypotenuse
-Fill with dirt from your local supply that's intended for raised beds.

I have dozens of these. They are great for making raised bed garden boxes. Funny story, I went to Lowes several years ago and told the garden guy I wanted to buy 24 of these. There was a partial pallet and he went over and counted and told me there were 24 on the pallet. They loaded the pallet onto my truck, I paid, and went home. After I unloaded them into my yard I realized that there were actually 48 on the pallet, not 24. Somehow he double counted. So an accidental slick deal was had.

I use 2x6's as the sides. Cut them to whatever length works for you. Mine boxes are 2 high and I never used rebar, never had an issue. I lined mine with weed barrier, laid clean cardboard on the bottom and filled with a QUALITY dirt, NOT bagged raised bed soil. That stuff is garbage.

I used a long garden stake at the bottom brick in a few and pushed another down through above, and also installed 4x4sin the corners on the inside to reinforce.

Rebar would have probably been better but I think using construction glue is probably smart... Now that I say it... It seems obvious.... What's wrong with me?
